摘要： A heating device comprises an inner tank, an outer shell, and a heater. The inner tank is received in the outer shell. An inner tank opening and an inner tank inlet are each in communication with an inner tank chamber. An outer shell opening corresponds in position to the inner tank opening. An outer shell inlet and the outer shell opening are each in communication with an outer shell chamber. An outer shell through-hole corresponds in position to an inner tank outlet. One end of an electrical heating tube of the heater is disposed at a fixing portion and electrically connected to a control circuit. The other end of the electrical heating tube is received in the inner tank chamber. The control circuit includes an electric wire for communicating with the outside. A guide channel is formed between the inner tank and the outer shell.
